endotherm

[′en·də‚thərm]
(physical chemistry)
In differential thermal analysis, a graph of the temperature difference between a sample compound and a thermally inert reference compound (commonly aluminum oxide) as the substances are simultaneously heated to elevated temperatures at a predetermined rate, and the sample compound undergoes endothermal or exothermal processes.
(physiology)
An animal that produces enough heat from its own metabolism and employs devices to retard heat loss so that it is able to keep its body temperature higher than that of its environment.

However, with respect to this rule, it is clear that its author devised it for endotherms, and that perhaps its extension to ectotherms produces these paradoxes.
Exotherms are characterized by the presence of two crystallization peaks at 61-62 [degrees]C and 98 [degrees]C, whereas the endotherm has only one broad melting peak at 110-111 [degrees]C.
However, the study of ectothermic vertebrates might provide a fruitful alternative for such studies, providing a system where one can potentially separate the consequences of altering metabolism and body temperature, since these two functions are not as intricately intertwined in ectotherms as they are in endotherms.
In figure 3b, the lower ethylene content copolymer exhibits a prominent melting peak at ~98[degrees]C, corresponding to primary crystallites, and a weak endotherm at ~50[degrees]C, corresponding to secondary crystallites.
There are also 2 endotherms associated with weight losses peaking at 176-179 [degrees] C and 466-483 [degrees] C, indicating, respectively, the presence of an amorphous phase and of a high defect kaolinite.
Like today's sea-faring tuna and great white sharks, dinos share some traits with both ectotherms (what people mean when they say "cold-blooded") and endotherms ("warm-blooded").
Differential scanning calorimetry showed typical melting endotherms identical to those of the B-polymorph in retrograded starch.
West Nile virus (WNV) has been reported in a variety of species but primarily endotherms.
4) for formulations numbered 6, 12, and 13, all PE-modified RPET blends with different functionalities but the same 10% modifier level, show that the PE crystalline melting endotherms are reduced by any modification of the PE component and most significantly when S-EP was used as the comodifier.
In this study, the double melting endotherms behavior of linear PBS and CEPBS observed might be explained reasonably by the melting and recrystallization model [19].
Over the next few decades, most paleontologists came to think of dinosaurs as more birdlike: warm-blooded animals, or endotherms, that grew quickly, expended lots of energy and regulated their body heat internally.
The DSC heating curves/melting endotherms were obtained for different ageing conditions and only representative curves for 50[degrees]C + W are given in Fig.
